How did Scotland yard get it's name?

Why is Scotland Yard named as it is if it is the UK high investigative agency?

Tom Burnam explains in The Dictionary of Misinformation:

From The Columbia Encyclopedia

Buram adds:

Nor is Scotland Yard in any sense a national police, like the FBI; it’s strictly a London outfit. . . Scotland Yard has no more authority over the rest of Britain than the Washington, D.C., police force has over the rest of the United States.

And I add:
it’s = it is

Well thanks…goes to show I’m an American!
